PFS, OS, and response to axi-cel in the mITT cohort. Kaplan-Meier curves of PFS and OS. Curves start at the time of axi-cel infusion and are stratified according to BT. Unadjusted mITT analyses compare the n = 132 patients without BT with the n = 143 patients who received BT. After PS matching, n = 97 patients were matched and compared in each group. Unadjusted PFS and OS (A,B) and PFS and OS after adjustment for baseline characteristics with PS matching (D,E). The ORR and CR rates in the mITT cohort before matching (C) and after PS matching (F). CART, CAR T-cell therapy.
